Figure 2 As described above, the wall-mounted heat exchange device involved in the embodiment of the present application is composed of a shell 100, a heat dissipation water pipe 200 and a blower 300.

[0023] Among them, Figure 1 As shown, a return air slot 110 and an air supply slot 120 are arranged side by side in the housing 100, and the return air slot 110 and the air supply slot 120 are separated by a water baffle 400, and a plurality of ventilation holes 410 are arranged on the water baffle 400, and an inspection port is arranged on the housing 100 at the outer end of the air supply slot 120. An inspection cover plate 500 is arranged at the inspection port, and a plurality of through holes are arranged on the inspection cover plate 500, and the inspection cover is connected to the housing 100 by a plurality of bolts cooperating with the plurality of through holes.

[0024] Among them, Figure 1 As shown, the air blower 300 is disposed in the ventilation hole 410 on the water baffle 400 , and is used to send the cold air around the heat dissipation water pipe 200 into the nuclear magnetic resonance imaging device 10 through the air supply slot 120 .

[0025] In this embodiment, the blower 300 is fixed to the water baffle 400 by two bolts. When the blower 300 needs to be removed for inspection and maintenance, only the two bolts need to be unscrewed.

[0026] In this embodiment, if Figure 4As shown, the through hole is a gourd hole 520. The upper end of the gourd hole 520 is a small hole and the lower end is a large hole, wherein the size of the small hole is smaller than the bolt head on the bolt used to fix the inspection cover 500; the size of the large hole is larger than the bolt head on the bolt used to fix the inspection cover 500. When the inspection cover 500 is fixed to the housing 100, the bolt passes through the small hole; when it is necessary to remove the inspection cover 500 to inspect the blower 300, use a screwdriver to loosen the inspection cover 500 by tightening the bolt, and gently lift the inspection cover 500 upward so that the bolt is positioned in the large hole. At this time, the inspection cover 500 can be removed, and the bolt does not need to be removed from the housing 100.

[0027] In this embodiment, if Figure 1 , 2 As shown, a buckle 510 is provided at the outer end of the inspection cover 500. There can be multiple buckles 510, which are convenient for operators to control the inspection cover 500 to cooperate with the gourd hole 520 to complete the operation when the inspection cover 500 needs to be removed or installed.
